Given its prevalence and impact, it is important that prejudice against sexual-and

gender identity minorities is reduced and that negative behaviors against these

minorities are prevented. We introduce and provide a definition of the term Sexual

Orientation and Gender Identity Prejudice (SOGIP), and discuss its determinants

and configurations as well as ways to measure it. Furthermore, we review the

recent social psychological literature on SOGIP-reducing interventions, identify

scientific knowledge gaps regarding these interventions, and offer recommendations

on how to apply the available knowledge to real-life situations. We conclude

that there are many interventions currently being employed to target SOGIP with

some seeming more effective than others. Particularly promising interventions

are those aimed at evoking empathy and perspective taking and those aimed at

developing alliances between minority and majority members. However, there is

still room for improvement. Overall, little empirical evidence speaks to the robustness

of intervention effects, its underlying mechanisms, duration, and boundary

conditions. Researchers should focus on all aspects of SOGIP (i.e., sexual orientation

prejudice as well as gender identity prejudice); different expressions of

prejudice (i.e., blatant and subtle), actual behavior towards minorities, and on

both perpetrators and targets of prejudice.
